AngularJS passing data to $http.get request

问题:

I have a function which does a http POST request. The code is specified below. This works fine.

 $http({
   url: user.update_path, 
   method: \"POST\",
   data: {user_id: user.id, draft: true}
 });

I have another function for http GET and I want to send data to that request. But I don\'t have that option in get.

 $http({
   url: user.details_path, 
   method: \"GET\",
   data: {user_id: user.id}
 });

The syntax for http.get is

get(url, config)

Can someone help me with this?

回答1:

An HTTP GET request can\'t contain data to be posted to the server. However, you can add a query string to the request.

angular.http provides an option for it called params.

$http({
    url: user.details_path, 
    method: \"GET\",
    params: {user_id: user.id}
 });

See: http://docs.angularjs.org/api/ng.$http#get and https://docs.angularjs.org/api/ng/service/$http#usage (shows the params param)

回答2:

You can pass params directly to $http.get() The following works fine

$http.get(user.details_path, {
    params: { user_id: user.id }
});

回答3:

Starting from AngularJS v1.4.8, you can use get(url, config) as follows:

var data = {
 user_id:user.id
};

var config = {
 params: data,
 headers : {\'Accept\' : \'application/json\'}
};

$http.get(user.details_path, config).then(function(response) {
   // process response here..
 }, function(response) {
});

Solution for those who are interested in sending params and headers in GET request

$http.get(\'https://www.your-website.com/api/users.json\', {
        params:  {page: 1, limit: 100, sort: \'name\', direction: \'desc\'},
        headers: {\'Authorization\': \'Basic QWxhZGRpbjpvcGVuIHNlc2FtZQ==\'}
    }
)
.then(function(response) {
    // Request completed successfully
}, function(x) {
    // Request error
});

Complete service example will look like this

var mainApp = angular.module(\"mainApp\", []);

mainApp.service(\'UserService\', function($http, $q){

   this.getUsers = function(page = 1, limit = 100, sort = \'id\', direction = \'desc\') {

        var dfrd = $q.defer();
        $http.get(\'https://www.your-website.com/api/users.json\', 
            {
                params:{page: page, limit: limit, sort: sort, direction: direction},
                headers: {Authorization: \'Basic QWxhZGRpbjpvcGVuIHNlc2FtZQ==\'}
            }
        )
        .then(function(response) {
            if ( response.data.success == true ) { 

            } else {

            }
        }, function(x) {

            dfrd.reject(true);
        });
        return dfrd.promise;
   }

});

You can even simply add the parameters to the end of the url:

$http.get(\'path/to/script.php?param=hello\').success(function(data) {
    alert(data);
});

Paired with script.php:

<? var_dump($_GET); ?>

Resulting in the following javascript alert:

array(1) {  
    [\"param\"]=>  
    string(4) \"hello\"
}

Here\'s a complete example of an HTTP GET request with parameters using angular.js in ASP.NET MVC:

CONTROLLER:

public class AngularController : Controller
{
    public JsonResult GetFullName(string name, string surname)
    {
        System.Diagnostics.Debugger.Break();
        return Json(new { fullName = String.Format(\"{0} {1}\",name,surname) }, JsonRequestBehavior.AllowGet);
    }
}

VIEW:

<script src=\"https://ajax.googleapis.com/ajax/libs/angularjs/1.3.15/angular.min.js\"></script>
<script type=\"text/javascript\">
    var myApp = angular.module(\"app\", []);

    myApp.controller(\'controller\', function ($scope, $http) {

        $scope.GetFullName = function (employee) {

            //The url is as follows - ControllerName/ActionName?name=nameValue&surname=surnameValue

            $http.get(\"/Angular/GetFullName?name=\" + $scope.name + \"&surname=\" + $scope.surname).
            success(function (data, status, headers, config) {
                alert(\'Your full name is - \' + data.fullName);
            }).
            error(function (data, status, headers, config) {
                alert(\"An error occurred during the AJAX request\");
            });

        }
    });

</script>

<div ng-app=\"app\" ng-controller=\"controller\">

    <input type=\"text\" ng-model=\"name\" />
    <input type=\"text\" ng-model=\"surname\" />
    <input type=\"button\" ng-click=\"GetFullName()\" value=\"Get Full Name\" />
</div>

For sending get request with parameter i use

  $http.get(\'urlPartOne\\\\\'+parameter+\'\\\\urlPartTwo\')

By this you can use your own url string
